Surgery Clinical Trial
Official title:
XEN45 in the Treatment of Chinese Patients With Primary Open-angle Glaucoma
Glaucoma is the second most common blindness disease in the world, second only to cataracts. The current treatment of glaucoma is mainly to reduce intraocular pressure.At present, two commonly used surgical methods are trabeculectomy and implantation of drainage valve. These methods are superior to drug treatment in reducing intraocular pressure, but the effect duration of these two methods is not long, and there may be serious complications and failure. Compared with traditional glaucoma surgery, MIGS may have better safety.The XEN45 gel implant is a collagen tube with a length of 6 mm and a diameter of 45 µm, which creates a new channel for drainage of aqueous humor by connecting the anterior chamber and the subconjunctival space. The implant is composed of porcine gelatin cross-linked with glutaraldehyde, and has good biocompatibility and tolerance. Therefore, after the advent of XEN45 products, more and more studies have shown that this treatment has excellent safety and effectiveness in reducing intraocular pressure in patients with open-angle glaucoma. Considering that the XEN45 gel stent has been in the market for a relatively short time, we conducted this prospective study to investigate the effect of XEN45 surgery in the treatment of primary open-angle glaucoma, in order to support ophthalmologists in formulating the best surgical plan for patients. The promotion of this surgical method.
